Description

Technical Field

[0001] The invention relates to a medical device, in particular to an air bag type flexible needle puncture device. Background Art

[0002] Minimally invasive interventional medicine is a new medical technology that has developed rapidly in recent years. It is a medical method between surgery and internal medicine. The oblique-tip flexible needle can overcome the shortcomings of traditional rigid needles that can only puncture straight paths and are difficult to correct puncture deviations. It uses its own flexible bending to bypass obstacles such as bones and blood vessels and accurately puncture the target. In actual clinical applications, the movement of the needle often affects the final puncture effect and the accuracy of the puncture path planning. Therefore, doctors need to spend a lot of time during the operation to adjust and calibrate the puncture needle movement of the puncture mechanism, which not only consumes a lot of time, but also cannot guarantee the puncture accuracy.

[0003] Based on the above problems, the problem to be solved by the present invention is the problem of flexible needle insertion. An airbag-type flexible needle puncture device is designed. The device body does not need to move as a whole. It only needs to use an airbag-type flexible needle puncture device to make the oblique-tip flexible needle puncture move, thereby improving accuracy and operating precision.

[0007] The beneficial effects of the present invention are:

[0008] The airbag-type flexible needle puncture device controls the flexible needle puncture by means of an airbag, thereby improving the compactness of the mechanism and ensuring the accuracy of the device.

[0009] When the airbag type flexible needle puncture device is described, the airbag device is easy to operate, does not require the entire device to be moved or rotated, needle insertion can be more accurate, and the mechanism is simple to operate. BRIEF DESCRIPTION OF THE DRAWINGS
